PROBLEM TO BE SOLVED: To solve such a problem that peeling is caused at a boundary of a adhesion glass layer and a non-magnetic substrate, and a boundary of a protecting film and the adhesion glass layer due to a cutting process from a lamination body block to a core half body and a gaped bar type, grinding, heat treatment, or the like, and yield and work efficiency are reduced largely. SOLUTION: As reducing reaction of the protecting film and the adhesion glass layer can be prevented by performing a reaction preventing material on a protecting film consisting of SiO<SB>2</SB>on a metal magnetic layer and forming the adhesion glass material or a Cr material as this reaction preventing material, stable crystal structure of the adhesion glass layer is obtained, adhesive force is improved remarkably. Thereby, as the strong lamination body block which can resist sufficiently for processing by cutting, grinding, heat treatment, or the like is formed, looseness and peeling of a junction part is not caused, a magnetic head having high quality and high processing yield is obtained.
